IMPROVED CHAIR-SEAT.

The vSchedule referred to in these Letters Patent and making part of the lsame.

'in the Application of a Seat or Cushion to the Back or Seat-Frame of a Chair; and I do hereby declare the same tobe fully described inthe following specification and represented in the accompanying drawings, of which- Figure 1 denotes a top view, and

Figure 2, a transverse. section of a chair-seat, with my improvement.

In the drawings A denotes the seat-frame, and

B, the cloth or cushion applied thereto.

The said seat-frame is formed with a groove, e, extending around it and arranged in it, near its inner edge, such groove being either square or rectangular. in transverse section The two cloths, a b, composing the ease' ofthe cushion, and containing between them'the stuliing c of hair or other proper material, are irst to be laidone on the other, and upon and lapped around a strip, C, of wood or other suitable material, having a section to correspond in form with that of the groove.

Next, the strip, with the cloth around it, is to be inserted and forced into the groove, the whole being so that when the strip is in the groove, such strip shall be covered in all four sides by the cloth, and the latter be made to project from the strip in manner as shown in Figure 3, which exhibits, on an'. enlarged scale, the groove, the strip, and a single piece of cloth, and shows the method in which the latter is arranged with and around thc strip, so as to cover it on its to surface.

held in place by nails or screws or cement, for unless so fastened, a slight pull exerted horizontally on the cloth will often serve to draw the strip and cloth out of the groove.

With my arrangement of the cloth, viz, so as to cover the strip, not only will it be impossible to detach the strip from the groove by a horizontal strain on the cloth exerted in the direction of the arrowjf, but the strip will be covered, so as to be out of sight by the cloth, and thus a better finish of the chair-seat will be made.

Furthermore, no nails or screws will be required to `keep the strip in place in the groove.

When the cloth is strained horizontally, while held by the strip-in manner as shown in fig 4, the tendency is to raise the strip out of the groove, but under the varrangement of the cloth and the strip in manner as shown in fig. 3, any tendency of a horizontal draught on the cloth to pull the strip out ofthe groove will be counteiacted or overcome by the cloth which laps over the strip, as such will prevent the strip from being drawn out oft-he groove.

I make no claim to the cloth and the strip so arranged in the groove that the top of the strip will be left uncovered by the cloth. Nor do I claim the arrangement of slits in a chair-bottom and of strips of rattan on such strips, in manner as described and represented in the specification and drawings of the United States Patent No. 55,605, `granted to Alanson Bingham.

With my invention, I make no use of such slits, but employ a groove, e, in the part or frame A, anda strip or frame, C, to be pressed into such groove with the cloth. I also use two layers of cloth to form the top and bottom coverings of the cushion and the space within them for the reception of the stuiiing.

What, therefore, I claim as my invention, is as follows:

I claim the combination of the two cushion coverings, a b, the grooved frame A, and the stripl or frame C, substantially in manner as above specified.
